To ctZZ whom it may concern:

Be it known that I, PETER SWEENEY, a citizen of the UnitedStates,residin g at New York, in the county of New York and State of NewYork, haveinvented new and useful Improvements in Journal-Bearings forVehicles, of which the following is a specification.

My invention relates to an improvement in journal-bearings for vehicles,and has for its object to provide a bearing in which the minimum amountof frictional resistance shall be offered to the rotation of the axleand a large conservation of power be thereby insured.

To this end the invention consists of the features of construction andthe combination of parts hereinafter described, and particularly pointedout in the claims.

I have illustrated the invention by the accompanying drawings, wherein-Figure 1 is a sectional end elevation, and Fig. 2 is a transversesectional view through my improved bearing. Fig. 3 is a diagrammaticView illustrating a slightly-modified arrangement of theantifriction-rollers.

The numeral lindicates the axle of the vehicle,on each end of which issecured a wheel 2.

The numeral 3 indicates the journal-box, one of which is located neareach end of the axle. The vehicle-body (not shown) is supported byhaving a frame member 4 secured to the journal-box by bolts 5. The axle1 passes through the sides of the j ournal-box, as shown. Journaled inthe sides of the journal-box is a short shaft 6, upon which is mounted arelatively large roller 7. Within the journal-box is located a largebearingring 8, which surrounds the axle 1 and roller 7, bearing againstthe periphery of each. This ring 8 and its cooperatingantifriotion-rollers, as Will presently appear, have to sustain theentire Weight of the vehicle. By the construction described it will beseen that the weight of the vehicle is first exerted upon the shaft 6,carrying the roller 7. Said roller bearing against the inner side of thering 8, the weight is transferred to this ring, which in turn transfersit to the axle, said ring being supported by the axle and bearing uponthe upper side only thereof. Thus only a small aggregate amount ofsurface is offered for frictional engagement between the rotating parts,and as all the parts brought into frictional engagement revolve theactual amount of resistance offered to the free rotation of the shaft 1is very slight. This result is further secured by the fact that the ring8 has no central journal-bearing and is in engagement only with theperipheries of the shaft 1 and roller 7 and the smallantifriction-rollers 10 11. These aniifriction-rollers are mounted onshafts 12 13, journaled in the side walls of the journalbox, and arelocated on opposite sides of the axle 1 above the ring 8, normally incontact with said ring 8, and they thus aid in sustaining the load ofthe vehicle. Owing to the relativelylarge diameter of the ring 8 ascompared with that of the axle and of the rollers -7, 10, and 11 theactual amount of surface engagement is very small. The lower portion 14of the journal-box is removably secured to the upper portion by means ofbolts 15 passing through lateral flanges on each and is designed to besupplied with oil or other suitable lubricating material.

My improved journal-bearing is primarily intended for use on automobilevehicles, but manifestly is not limited to such application or toapplication to vehicles, but may be em ployed advantageously with anycharacter of device having a revolving shaft or axle supported in ajournal-box.

As shown in Figs. 1 and 2 of the drawings and as above described, theantifriction-rollers 10 and 11 are disposed above and in contact withthe ring 8, and they thus aid in sus+ taining the load. If desired, Imay employ in addition to the rollers 10 and 11 a second set of rollers10 11, as shown in Fig. 3, which, like the rollers 10 and 11, are alsojournaled in the side walls of the journal-box and disposed on oppositesides of the axle 1, but normallyout of contact with the said axle andwith the roller 7 and ring 8, but in close jux taposition thereto. Thepurpose of these rollers is to afford a lateral bearing for the ring 8when starting or stopping the vehicle.

What I claim, and desire to secure by Letters Patent, is-

1. In combination with an axle, a journalbox mounted thereon, an annulusor bearingring surrounding said axle and supported thereon, andantifriction-rollers located upon opposite sides of the axle and bearingagainst the periphery of the annulus or bearing--ring,

said rollers being arranged so as to aid in sustaining the load. I

2. In combination with an axle, a journalbox mounted thereon, a rollerjournaled in the journal-box, an annulus or bearing-ring surroundingsaid axle and roller and bearing against the periphery of each, andantifriotion-rollers located upon opposite sides of the axle and bearingagainst the periphery of the annulus or bearing-ring, said rollers beingarranged so as to aid in sustaining the load.

3. In combination with an axle, a journalbox mounted thereon, a rollerjournaled in the journal-box, an annulus or bearing-ring surroundingsaid axle and roller and bearing against the periphery of each, anantifriotion roller located on each side of the axle and bearing uponthe inner face of the ring, and autifriotion-rollers disposed outsidethe ring and bearing against the periphery thereof PETER SWEENEY.
